DOOR-SUPPORT.

Specification of Letters Patent.

Application filed March 18, 1914; Serial N02 825,569.

Tb all whom it may concern 3 Be it known that I, FRANK J. BECKER,

a citizen of the United States, residing at Independence, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Door-Supports,'o1

a door and to a door jam which is inconspicuous, is not likely to get out of order;

and which effectually prevents a door from sagging.

The invention consists in the construction and combination and arrangement of de-' vices hereinafter described and claimed.

In the accompanying drawing :Figurel is a perspective view of a portion of a door and of a jamb, provided with1 door supporting means constructed in accordance with my invention, the door being shown part-1y open. Fig. 2 is a horizontal sectional view of the same with the door closed. Fig. 3 is a vertical section on the plane'indicated by the line aa of Fig. 2. Fig/4 is a similar view on the plane indicated by the line b-b of Fig. 3.

For the purposes of this specificationa door is indicated at 1 and the jamb of the door frame, against which the door closes, is indicated at 2. In accordance with my invention I provide an improved keeper plate 3 which is adapted to be rabbeted in the door jamb to lie flush with the surface there of, and this keeper plate is provided at its upper end with an outwardlyextending arm 4, the upper side ofwhich is inclined to.

form a cam as at 5.. An auxiliary keeper plate 6 is provided which israbbeted and' secured to the jamb at a suitable distance above the keeper plate 3. A casing 7 is adapted to be mortised in the door at the free edge thereof, on one side and at a point opposite the keeper plate, this casing having a face wall 8 which extendsacrossand .is rabbeted in the edge of the door and also having a side wall 9 which is rabbeted in one side of the door and is provided wit-h a longitudinal slot 10. The casing is provided with a longitudinal cylindrical bore which opens through the face plate. A bolt 11 is arranged in this bore for longitudinal moveof a pin 15 and servingto keep in place on the spindle of the bolt. A knob or head 16 is provided with a stud 17 which ment and is formed with a reduced spindle Patented July "t, 1914.

12 for the greater portion of its length, on

which spindle is mounted a sleeve roller 13 for revolution, a washer l-lbeing secured on the outer end of the spindle as by means has threaded engagement with a transverse opening in the bolt and operates in the slot the roller 10 of the side wall 9. This head projects beyond the side wall 9 and enables the bolt to be adjusted so as to project the sleeve roller to any required distance beyond the face wall, according to the width of the crack between the free edge of the door and the jamb when the door is closed.

In the operation of my improved door support the sleeve roller on the bolt ongages the cam 5 of the keeper late as the door nears a closed position an moves upwardly on said cam face as the door closes, thereby causing the bolt to lift the free side of the door, and as the said bolt bears on the upper end of the keeper plate when the door is closed said keeper plate and bolt coact with each other to support the free side of the door and effectually prevent the same from sagging. The bolt when adjusted is secured in a justed position bytightening the screw stem of the knob or head so as to clamp the latter to the outer side of the side wall 9. The bolt once properly adjusted remains in such'adjusted position unless the door or frame should swell or expand, in which event the bolt should be re-adjusted according to the width 'of the crack.

While I have herein described and shown a preferred form of my invention I would have it understood that changes may be made in the form. proportion and construction of the several parts without departing from the spirit of the invention and within the scope of the appended claims.

Having thus described my invention, I claim l. The hereindescribed door support comprising a keeper for attachment to a jamb and having an inclined cam surface to project beyond one side of the jamb, in combination with a frame for attachment 'to'the free side of the door and a bolt projecting from said frame to engage and ride up on the cam of the keeper when the door closes and thereby raise and support the free side of the door, and means to adjust said bolt in the frame so that it may be caused to project to any desired extent from the free side of the door.

2. The herein described door support comprising a keeper for attachment to a jam-b and having an inclined cam surface to project beyond one side of the jamb, in combination with a frame for attachment to the free side of the door and a bolt projecting from said frame to engage and ride up 'on the cam of the keeper when the door closes and thereby raise and support the free side'of the door, and means to adjust said bolt in the frame so that it may be caused to project to any desired extent from the free side of the door, and a sleeve roller on the said bolt and adjustable therewith in the said frame.

The herein described door support comprising a keeper for attachment to ajamb and having an inclined cam surface to project beyond one side of the jamb, in combination with a frame for attachment to the free side of the door and provided with a guide bore and also with a side Wall having a longitudinal slot, a bolt arranged in said bore means to adjust said bolt in the bore to cause the outer end of the bolt to project beyond the face end of the frame, a sleeve roller on the outer end of the said bolt and adjustable therewith in said bore and an operating and securing head bearing on the outer side of said frame and movable thereon, said head having a threaded stud engaging a transverse threaded opening in the bolt.

In testimony whereof I afliX my signature in presence of two witnesses.
